Distribution and Diversity of Sand Fly Species (Diptera: Psychodidae, Phlebotominae) in Two Geoclimatic Zones of Chad

Leishmaniasis transmitted by sandflies is an important vector-borne disease. In Chad, information on outdated, and so this study was designed to update the sandfly fauna. Sandflies were collected in five health districts representing two geoclimatic zones using sticky traps pyrethrum sprays indoor peridomestic habitats between September 2019 December 2020. All specimens identified based species-level morphological characters. A total of 2,015 belonging 13 species (one Phlebotomus twelve Sergentomyia ) identified. The vector human cutaneous leishmaniasis, duboscqi , represents 0.65% all only representative genus be predominantly inside dwellings. orientalis visceral leishmaniasis previously Chad 1976 not found study. clydei, schwetzi, antennata africana most abundant with 44.71%; 22.73%; 16.03% 11.17%, respectively. schwetzi dubia involved transmission canine four sites According our results, fauna comprised species. Our data showed that, unlike P. which found, present surveyed. Therefore, these areas are at risk remain potential foci leishmaniasis. However, need for further studies such as detection, their seasonal fluctuations competence.
